I started out looking for something to broadcast through my radio collection. After doing a little research it seems wise to pick something that can be more versatile for the future. Then again the closest neighbor is 1/2 mile away...

:I recently got interested in Low Power Radio. I built the Antique Electronic Supply 100mw AM transmitter and I've been driving my neighbors crazy walking around the block with a 1kc tone on my portable radio- trying to tune the antenna, etc. I'm thinking of getting a 5 watt FM stereo transmitter next week. Any ideas?
You might like to build a 6888 transmitter? Very good signal and near 100% modulation. Check the below site and sort on 6888. Look only in homebrew section.

Post your questions. Hundreds of these transmitters have been built.

:::::Terry, how do you like the AES transmitter so far? I have been looking at the SSTRAN AMT3000, it is about $40 more and is a solid state kit. I am curious to see what others have to say as well. I just starting looking at the LPFM transmitters, will be interesting to see what others have to say.

::::The K-488 is nice for getting used to setup, winding coils, etc. It's only good for around the house though. I live in a big old building and I'm on the 3rd floor. I'm waiting for some magnetic wire to wind a new loading coil. If I were you, get the AMT, it's probably worth the extra. I'm looking at an item on eBay that is 5 watts FM stereo with PPL. Keep me posted. Terry

:::Hi Terry, I have a SStrans 3000 and love it. I use it all the time and it works great. You can beef it up and get a range of approx. 2 miles. I use my'n to play music from my computer. If you guys want to listen to some great music from the 1920's/30's google Loud City Radio Dismuke and tune in, that old music sounds great coming out of old time radios.

::Great, I'll check it out. I haven't decided to go FM or AM. FM sounds better of course, but AM goes farther with less power. What kind of antenna do you have? I have a 10' length of #12 inside a 1/2" PVC. I wound about 120 turns of steel wire on a form but then decided to use enameled magnetic wire, which I'm waiting for. I'm going to wind 62' onto a 1 1/2" piece of PVC with taps at every 10 turns. I picked up a field strength/swr meter on eBay, but I doubt if it will even measure the output. I'm really excited though. My whole neighborhood is waiting for me to start broadcasting old radio shows. Terry

Done! I even joined and added my story about hooking up an Allied Radio Broadcaster to a 20 watt jukebox amp. when I was a kid. It worked pretty good considering I knew nothing about impedance or loading. However, when a parent found out we were transmitting phone calls, he shut us down.

The manual is extremely well done. It took me less than 4 hours to put the kit together. That included reading the manual once all the way through before starting, and the time to get all the tools together as well. The only problem I had was cutting the "Jumper Header" pins apart, I just couldn't get them to cut right. Fortunately I had a stash of headers from another project that didn't need to be cut apart. I set the switches for 1660Khz and powered up... for the "smoke test". I immediately heard the signal through the radio across the room, before tuning the antenna. My eyes aren't what they use to be, so a magnifying glass was a must.
I am very impressed with the quality of the kit and the manual, not to mention the audio quality.
Of course now I am thinking... how hard can it be to build an "auto tuner" for the antenna... and the ability to digitally set (and display) the frequency.
All in all, after 30 minutes of air time, my feelings are that the SSTRAN AMT-3000 is an excellent product worthy of the many glowing reviews I have read. I am sure it has its short comings, but it certainly does what I wanted it to do, and does a very nice job of doing it as well.
